Abstract

Background

Despite advances in antimicrobial and surgical therapy, septic arthritis remains a
rheumatologic emergency that can lead to rapid joint destruction and irreversible
loss of function. In adults, Staphylococcus aureus is the most common microorganism isolated from native joints. Streptococcus gordonii is a prominent member of the viridans group of oral bacteria and is among the bacteria
most frequently identified as being primary agent of subacute bacterial endocarditis.
To the best of our knowledge, Streptococcus gordonii has not yet been described as agent of septic arthritis.

Case Presentation

We describe here two cases of septic arthritis due to Streptococcus gordonii. It gives us an opportunity to review epidemiology, diagnosis criteria and management
of septic arthritis.

Conclusion

Although implication of S. gordonii as aetiologic agent of subacute endocarditis is well known, this organism is a rare
cause of septic arthritis. In this case, the exclusion of associated endocarditis
is warranted.
